A LOT of that came from received culture growing up in California as a boy in the 1990's. I no longer want to be at the top of a pile of monkeys. I want my daily labor to support others in my community (broadly) rather than working to enrich a few people who will own everything and control our economy.
I think if you grow up in a society that tells everyone "greed is good" then you're going to think being greedy is human nature, but actually anthropologists know that societies have again and again existed based on mutual support of one another. I am simply suggesting we drop this "greed is good" mantra and focus on helping one another. And I think it can be more economically efficient when you value each person's life more or less equally.
if you really want to improve social equity, distributing esteem more widely[0] will be more fruitful as a guiding light than trying to devise a more perfect, automation-based socialist/communist economic model. extreme automation will inevitably increase inequality as capital will find ways to corner ownership of the machines and hoard the productivity gains, no matter your good intent.
[0]: 'flatten the pile', if you will.
given this universal truth, the question isn't 'how do we limit our wants, and our desire to induce others' wants to fuel our own wants?', but rather 'how do we repurpose this innate desire for the greatest collective good?' capitalism tries to provide one answer: redirect greed into productive drive by rewarding economic novelty and efficiency. however, even that idealism has been subverted by the political economy and the complex interactions between government and business, to the detriment of social harmony.
[0]: note that what we all really want is to be at the top of the monkey pile, and everything you're talking about are various proxies for how to tell where we are in the pile. we're never going to overcome that with solutions like 'end consumerism'. you're literally working against human nature with that line of thinking.
